electrical problem on non turbo berlingo van?

hi i have a berlingo van and it went to a back street garage to have the clutch changed. when i had it back most of the electrics were not working. ie wipers heaters,dash lights coming on and then going off about a minute later. no head lights only side lights, battery light and brake light stay on but alternater has been checked. all fuses seem ok any cheap tricks to repair this ?
